Serial No. 275,508.

This invention relates toheel makingma chines and is illustrated as 'embodied in a wood heel turning machine of the type disclosed in United States Letters Patent'No.

1,488,534, granted April 1,1924, on the applicationo-f Folsom, Vinton and Whitney.

Machines of this type are provided with two rotary cutters and a jack for holding a heel blank, the blank being swungpast one cutter by the jack to makea cut around one side of the heel blank fromlbreast to back and then past the other cutter to out around-the other side of the blank. It has been customary to clamp the heel blank in the jack by its toplift and heel seat surfaces and to gage it only by a gage at its breast surface, Since the lateral and rear surfaces of. the blank were about to be trimmed by the cutter. Such a gage affords no certaintyof lateral positioning of the blank, this being'entirely a matter 1 of theoperators judgment. Under some con ditions this circumstance has resulted in in ferior work inasmuch as the lateral surface.

thus formed on the blank sometimes-lacked proper relationship to other surfaces formed thereon. This was especially true in the case of Cuban heels, in which the previously formed breast groove is vertical, and a sllght lateral displacement of the blank in'the heel turning machine would put the sl'deandg breast surfaces hopelessly outo'f proper rela tionship.

This problem has been satisfactorily dealt with by the invention of A. F. Cook disclosed in his application Serial No. 274,583, filed May 2, 1928; Cook provided, in addition to the usual breast gage, a side gage-arranged to contact with a lateral face of a wood heel blank and removable from operative position after the blank had been gaged to permitthe trimming cutter to form the lateral heel"sur' I face'on the blank, the gage being moved from operative to inoperative position by a; handle. It is an object of this inventlon tonnprove still further the construction provlded by the invention of Cook. To this end I have provided an organization comprising, as 11- lustrated, a single handle for clamping the heel blank in the jack, for moving aside gage from operative to inoperative position, and

structi on and operation of the machine.

In accordance with another feature of the invention, the illustrated gage is pivoted on an axis oblique to the gaged face of the heel blank so that as it is swung from operative positionit will separate from the gagedsurface by the initial portion of its movement, thus avoiding any possibility of disturbing she gaged blank by dragging along its sur ace. I

These and other features of the invention comprising certain combinations and arrangements of parts will be apparent from the following description of a preferred embodiment of the invention shown in the drawings, in which i i Figs. 1 and 2 are side views of so much of a machine of the type referred to as is necessary to an understanding of the present invention and showing the side gage in retracted and in operative position, respectivey; and

' Figs. 3 and '4 are'simila r views taken from the front of the machine.

The jack 10 of the illustrated wood heel turning machine is supported on a jack holding shaft 12 pivoted to the machine by means of a bracket or crane not'shown herein but ,fully set forth in the Letters Patent referred to. The jack is pivoted to a plate 14 at the topof the shaft 12 by a horizontal pin 16 to permit vertical tilting of the jack. The jack carries a base plate 18, on which a wood heel blank 20 is placed against a breast gage 22, adjustable by a slot and bolt connection at 24. An upper clamping member 26 is pivoted to move vertically above the blank 20 and is forced against it by pressure from a screw 28 swiveled in the end of a compound lever 29,30 pivoted on the jack frame at 32. A roll 34 at the end of the lever28, 30 is engaged by a cam 36 at the end if a lever 38 pivoted on the jack frame at 40, to rotate the lever 28, 30 and set the clamping member 26, thereby holdingthe blank against the base plate. This clamping structure will be found more fully described and claimed in United States Letters Patent No. 1,707,985, granted highly desirable that theablank should be gaged fro'mthe side as well as from "the breast, and to this end I have provided an improved side gage 48 of the type which is removable from the path of the cutters after its gaging function is performed;

This gage 48 is mounted fixedly on a stub shaft '50 rotatable in the jack frame. The

stub shaft is not quite horizonta-h' extending a little downwardly and outwardly from the jack frame. An adjustable contact member 52 is mounted in the gaging end of the member 48. A link 54 is pivoted to the gage and to a boss 56 on the operating lever 38.

When the lever38 :is swung up, as shown -inFig.'2, to loosen the lever 28 and release the-blank 20, the boss 56 swings to the right and throws theggage 48 clockwise until its left end 58 comes up under a stop 60, Its gaging end will then be opposite theside of the newlyinserted heel blankQO which can be laterally gaged by the contact member '52. When the lever 38 is thrown down, as shown in Fig. 1, to-clamp the'heel, it swings thegage 48 up away from the side of theblank 20, so

v thatthe cutters 42 can cut the surface lately engaged by the side gage. Owing to the slope ofthe-shaft 50 this upward movement of the gage 48 has anoutward component so that the contact member 52 immediately moves laterally away from the blank 20 as it begins to move upward (Fig. 8), thus avoiding any disturbance of the blank as the gage is removed. w

A coil spring 62, wound around the shaft 50 and connecting it to the. frame of the jack, tends to hold the gage in operative position,

and a pin and slot connection 64 between the.

link 54 and the boss 56 insures that the gage shall reach itsoperative position irrespective of accurate positioning of the lever 38 when I the ack is unclamped.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
